Collier has a little wiggle and is short to the ball with a high finish. He makes good contact.

Power:

He has real power now and more to come. Most of his power is to center field, but he's got some pop to the pull side as well..

Running Speed:

He's got pretty good speed, clocking a 6.8-second 60-yard dash.

Base running:

He's not bad, but with more instruction, he should be better and be able to steal more bases.

Arm Strength:

He shows an arm that's a tick below-average in games, but it should be average in time.

Fielding:

He plays right field on his high school team, but he should be playing center in high school.

Range:

He has the instincts and range for center, though eventually he'll profile as a corner guy as he fills out.

Physical Description:

Collier has a developed body, broad shoulders and a trim, high waist. There's plenty of room for growth.

Medical Update:

Healthy.

Strengths:

Athleticsm, power, tools, strength.

Weaknesses:

He's young -- just 17 -- and hasn't had much instruction; he should be getting looks in center instead of right.

Summary:

Collier began the year behind other California high school outfielders like Aaron Hicks and Anthony Gose. He closed the gap with some strong performances this spring, showing some big-time power in some big games. He's still very raw, but with some more instruction, a whole lot could be unlocked.
